Currently ids in star files are limited to 80 bytes. This leads to problems with some full qualified class names because some are now longer than 80 bytes after changing the package separator and therefore truncated in the header data of the star file, which leads to the problem that these classes can not be loaded from the star file.
There are two solutions: extend it about the currently free 8 bytes, which is easier to implement but still limits the id field, or extend the complete header field for one entry from 256 bytes to 512 bytes.
